Description

An all-in-one high-power sound bar

technical field

The utility model relates to audio equipment, in particular to an integrated high-power bar-shaped audio.

Background technique

In recent years, the technological development of TVs has been surging, and the products are getting thinner and thinner. Even borderless TVs have appeared. Smart TVs and Internet TVs are all in full bloom. But they all have a common problem that is difficult to overcome. With the advancement of technology, the sound of almost all smart TVs sold in the market is not satisfactory due to the limited size and frame after being made thinner, and the sound of the matching commercially available soundbars is too small. , which is a defect for TV products with increasingly clear picture quality. Although high-power multi-channel home theaters can produce theater-like sound effects, such products are bulky and incompatible with the new technology's ultra-thin The appearance of the smart TV does not match,

With the digital advancement of audio technology, bar-shaped multi-speaker speakers with the same thickness as smart TVs have been produced one after another. While making the living room or living room more beautiful, you can also hear quite good sound. However, for a product whose height and thickness of the speaker do not exceed 70mm, a product with a power of more than 60W is of course a icing on the cake for watching blockbuster movies on the TV. The reduction in the volume of the speaker will undoubtedly save a lot of raw materials for the casing , It will be a positive response to the energy conservation and environmental protection policy advocated by the state.
